Nothing at all like the Lori Drew Incident that confirms that MySpace is more Train Wreck than Social Network, a spoiled little brat has to ruin it for everybody else because he doesn't want to be disciplined. Another thing to consider is if his dad was some high ranking bureaucrat trying to "save the children from the evils of sex and violence".
The court hasn't though about the children and the adults who know it is just a game.
So your dad grounded you from video games.
SUCK IT UP! Do your punishment and get it over with. Unless your dad caught you going to some illegal gambling website (which I doubt any 12 y.o. would be doing) or going to one of the nefarious websites that have numbers that are unnecessary and strange suffixes, there is no reason for bratty behavior.
So you are banned from World of Warcraft for a week. Is killing yourself in real life going to resolve anything?
Thailand may think they may have people's best interest at heart but it is foolish to make a federal case out of an incident where parents must be accounable for their children's actions, not the government. Unless the kid steals a PS3 from a shop, mom and dad need to increase their discipline.
Remember, If you love you're children
BEAT THEM!
